what is an argument?

Hi there! An argument is what we pass to a function when we call it. Let's take a look at a really basic function.

public int addNumbers(int num1, int num2) {
    return num1 + num2;
}

This defines a function named addNumbers and it has parameters named num1 and num2. This will add any two integers we send in. We send in the numbers by calling the function:

int results = addNumbers(15, 21);

This line calls the function or tells it to run/execute. The numbers 15 and 21 are our arguments. They are what are being sent to the function. When the function runs, the first argument (15) will be assigned to the variable(parameter) num1 and the second argument(21) will be assigned to the second variable(parameter) num2. The value will then be returned by the function and assigned to results, which in this case will be a value of 36.

Hope this helps!
